Your Smart Refrigerator Has More Features—But Are They Necessary?

A refrigerator’s main job is to keep food cold and fresh.

New models can also have screens, cameras and apps.

These extras can help people check what food they have and avoid wasting it.

But they can also make a refrigerator more expensive.

The author says shoppers should first check how well it cools and whether it suits their home.

It is also worth considering how easy it is to clean and whether service is reliable.

A refrigerator may last many years, while its apps might not.

Smart features can be helpful, but they should be extras rather than the main reason to buy one.
